Abstract

Background: Estrogen deficiency after menopause is a major reason of bone loss in postmenopausal women. YSM (years since menopause) is negatively related with BMD in postmenopausal women. Bone loss after monopause is accelerated in early stage of menopause, and then decreases. There are some evidence that body weight can prevent bone loss in menopausal women. Therefore, we evaluated associations of the general characteristics and lumber BMD of postmenopausal Korean women, and determined the rate of bone loss after menopause at 5-year interval.
Methodd: BMD was measured by DEXA system, and physical, anthropometric data including body fat were obtained in 1006 peri- and postmenopausal women. Pearsons correlation coefficients were made among physical, anthropometric data and lumbar BMD. To determine the contributable factors for lumber BMD, multiple regression analysis was done.
Results: 1) In Pearsons correlation analysis among body composition YSM and spinal BMD, YSM was strongly associated negatively with spinal BMD. 2) On the other hand, weight and BMI was associated positively with spinal BMD. 3) The percent difference in spinal BMD between perimenopause and 5-years after menopause was 15.3%. 4) Years since menopause, body weight was revealed as an important factor that predicted spinal BMD by multiple stepwise regression analysis.
Conclusion: We conclude that YSM and body weight were revealed as important facotrs that can predict spinal BMD in postmenopausal women.
